Three high-speed robots for the R 40 rotor spinning

A new version featuring three high-speed robots is now available for producing medium and fine yarn counts on very long Rieter R 40 rotor spinning machines. The third robot operates very efficiently, since it can change sides rapidly via the short loop. All the robots also have individual maintenance positions, so that machine efficiency does not decline unnecessarily, even during service work.
At constant output of medium to fine yarn counts on machines with up to 400 spinning positions, two of the high-speed robots ensure the best efficiency levels. Each robot serves one complete side of the machine. The operating ranges of the robots can be set easily and flexibly at the touch screen of the central machine control unit and can be changed during production operations.
In this case the operator can select overlapping or adjoining operating ranges. The brief maintenance work on the robot is performed ergonomically on the loop, without hampering other operations, such as removing the packages, in the process.
There is virtually no decline in machine efficiency during this work.
Using 4 robots with this machine configuration is not yet worthwhile. The situation is different with 440 or more spinning positions, coarser yarn counts, delivery rates of over 220 m/min and small package formats: in this case the additional robots result in a significant increase in productivity.
Rieter is now offering an R 40 with three robots, a maintenance station and a loop for operations in the range between the extremes described above.
